Ecology: The study of the relationships between beings and their non-living environment.
Ecosystem: A self-sustaining set of beingnesss and their nonliving environment. Made up of both parts:
Abiotic: Non-living examples rock, soil, water, air.
Biotic: living examples animals, plants, humans, bacteria.
Role of bacteria and fungus in an ecosystem
Bacteria and fungus are substantial in cycles of materials in ecosystems. It is essential to re-use, and recycle all the resources on earth. A major chemical group of organisms are the decomposers. This group plays an beta role in the ecosystem as they abeyancedown dead plants and animals into simpler substances which allows the recycling of matter through an ecosystem. Decomposer is an organism that obtains its food from the wastes and remains of dead organisms. E.g. decay bacteria and fungi. They break down decaying or dead animal to release important minerals back into the soil.
The environment: The environment is all the external factors contact and affecting a given organism at any time e.g. air, water, minerals, organisms.
Adaptation: Is the structure, feature, and characteristic of an organism that allows it to successfully experience in its environment this include three classifications:
Structural- how an organism is build e.g.
fins, limbs, shape, size
Functional/physiological- how an organism works e.g metabolism, kidneys, lungs, muscles.
Behavioural-what an organism does, e.g. nocturnal, diurnal, burrows
It is sometimes uncontrollable to infer that the characteristic of an organism is an adaptation to its particular habitats because:
The organism whitethorn be observed outside the habitat in which it evolved. For example in a suburban garden
The characteristic may provide no particular advantage in a particular habitat but has been inherited from ancestral organisms that live different habitats
It may simply be difficult to be certain how a...If you want to get a full essay, request it on our website: Orderessay
